Floyd Mayweather upped his career record to a perfect 48-0 Saturday night in Las Vegas, earning a decision over Manny Pacquiao in a bout many billed as the “Fight of the Century.”

Mayweather, using his incredible defense and quick lands, retained the WBA (super), WBC and The Ring welterweight titles, while also winning the WBO welterweight belt from Pacquaio (57-6-2).

The scores were 116-112, 116-112 and 118-110 in favor of “Money.” Mayweather landed 148 punches to just 81 by Pacquiao.

Mayweather, who credited Pacquiao after the fight for being a “hell of a fighter,” also said that he will compete for the final time this September.

“My last fight is in September, then it’s time for me to hang it up,” he said. “I’m almost 40 years old. I’ve been in the sport 19 years. I’ve been world champion for 18. I’m truly thankful and I’m blessed.”

Leo Santa Cruz scored a decision over Anthoy Settoul in the co-main event, while Vasyl Lomachenko defended his WBO featherweight title with a ninth-round knockout of Gamalier Rodriguez. Also, Jesse Hart stopped Mike Jimenez via TKO in the sixth to become the USBA super middleweight champion.

Former UFC welterweight champion Georges St-Pierre admits that the fire to compete inside the Octagon is coming back.

But he isn’t about ready to declare himself back in the welterweight division.

St-Pierre appeared on a recent edition of “UFC Tonight” to discuss his plans, and the French-Canadian remained uncommitted to competing again for the promotion.

“It’s not interesting for me right now,” he said. “I’m not sure. I just really don’t know. That’s why I didn’t say if I’m retired yet. I just don’t know.”

The 33-year-old has returned to working out and training at Tristar Gym following knee surgery and filming movie roles, but that is just the start of a long process if he is to fight again.

St-Pierre’s last appearance inside the Octagon came in 2013 when he defended his title with a split decision victory over Johny Hendricks. He vacated the belt shortly after that fight, which was his ninth successful title defense.

“I want to sit back, relax and watch the show,” he said. “More and more, I have more fun in training and the fire is coming back. But it should be a rational decision as well.”

Brian Stann was once a teammate of Jon Jones at Jackson-Winkeljohn in New Mexico.

Stann, a member of the FOX Sports announce team, appeared on a recent edition of “UFC Tonight” to provide insight into the mind of the former UFC light heavyweight champion.

“I’d love to say I was shocked, but I was not,” Stann said. “On a scale from one-to-10, probably a four of a five.

“I was shocked at the details surrounding it and how it went down.”

Previously, Jones was found to have cocaine metabolites in his system during a random drug test late in 2014 prior to facing Daniel Cormier. Also, he had a driving under the influence charge previously in his UFC career.

Despite that, Stann doesn’t think Jones is a “bad guy.”

“I’d be a liar if I said I didn’t witness him act with kindness and caring and be a person with character,” he said. “In his loss to Matt Hamill, which was a simple rule break, he handled it with class and care. When he first came into that gym, people knew there was something unique about him. He had a lot more to lose than everyone around him, and the leaches came out who wanted to take something from him early on and he dealt with a lot of temptation.

“He’s very lucky. This is the second time he’s been in an automobile accident and somebody could have died. That’s an unfixable mistake.”

The UFC stripped him of his title and suspended him until all of the legal actions play out, leaving Jones away from the sport he has dominated for several years. Many wondered what the promotion would do, but they quickly made the move to distance themselves from “Bones.”

“I was surprised how quickly it happened. If you care about Jon, and saw this coming at some point, you are happy with it,” he said. “This is the only way for him to realize there’s a problem. This is a massive embarrassment and a huge loss of money. And he’s lost his right to work. If you care about him, you wanted something to happen that would make him reevaluate how he lives his life and make the appropriate changes.”

Jones, who is involved in an alleged hit-and-run, has been taken off the rankings completely. The light heavyweight division will crown a new champion at UFC 187 when Anthony Johnson faces off against Daniel Cormier.

Several other changes were made to the rankings, as Max Holloway moved ahead of Cub Swanson and into fifth at featherweight. Darren Elkins and Hacran Dias each climbed two spots, as well, at 145 pounds.

Josh Thomson and Eddie Alvarez flipped for ninth at lightweight, while Michael Bisping and Thales Leites did the same at middleweight and Aljamain Sterling and Bryan Caraway at bantamweight.

Former UFC light heavyweight champion Quinton “Rampage” Jackson made his return recently, and did the same in the rankings, debuting back at No. 10.

Maryna Moroz, Felice Herrig and Jessica Eye each moved up a spot in the women’s rankings.

Tim Kennedy believes a fight with Lyoto Machida makes sense for both men.

Kennedy (18-5) had his four-fight win streak snapped by Yoel Romero this past September and has remained on the sidelines since. Machida, meanwhile, is coming off a loss to Luke Rockhold.

Appearing on a recent edition of Submission Radio, Kennedy clarified what he meant by asking for a “loser-leaves-town” bout with Machida.

“I was just making fun of him, talking crap,” he said. “I think as I said, man we’re both crusty old farts. You know we’ve both been fighting for so long that at this point of this career I think if both of us had another loss, is there any realistic chance that we’d be fighting for a title? If I don’t have hopes of fighting for a title, then what’s the point of me fighting? I’m not going to be that guy that’s just holding on for another fight for another pay check.

“I want to be fighting the best guys in the world, and you know Lyoto’s still one of those guys.”

Kennedy scored wins over Michael Bisping, Rafael Natal, Roger Gracie and Trevor Smith between 2013-14 before falling to Romero. He’s fought for the Strikeforce title twice, losing a decision to Rockhold in 2012 and a decision to Ronaldo “Jacare” Souza in 2010.

In Machida, he would be facing his second former or current UFC champion, as Kennedy bested welterweight titleholder Robbie Lawler back in 2011.

I have so many advantages over him that I’m not sure I can even list them,” he said of Machida. “First and foremost, I don’t ingest urine. You know I think my ability to consume other fluids is first and foremost paramount in the match up. So the toxins that are going to be leaving my penis, I’m not going to put back down my throat. So that’s major.

“And second is, I think Karate’s dead. So he may be good at a whole bunch of things and Karate is also one of them, but karate is not what made him successful. He’s a black belt in jiu-jitsu, he has fantastic wrestling, he has great kickboxing, but he can still walk out with his Karate gi, he can try to front kick me – that’d be cool – what else? I’m trying to think of other things. I have better hair. “
